Question

Can u explain how to do this question..pls​

Answer 1

RS ≈ 5.39

Explanation:

Calculate the length using the distance formula

d =
`\sqrt{(x_(2)-x_(1))^2+(y_(2)-y_(1))^2 }`

with (x₁, y₁ ) = R(- 2, 6) and (x₂, y₂ ) = S(- 4, 1)

RS =
`√((-4+2)^2+(1-6)^2)`

=
`√((- 2)^2+(-5)^2)`

=
`√(4+25)`

=
`√(29)`

≈ 5.39 ( to 2 dec. places )

Answer 2

use this formula, you will get the answer

Explanation:

√(x2-x1)²+(y2-y1)²
